Setting the sensitivity level
Two shooting sensitivity levels equivalent to film speeds of ISO 800
(STD) and ISO 1600 (HIGH) can be selected. Set the sensitivity to
“STD” when taking pictures outside in bright weather, and “HIGH" for
dark interiors.
While pressing the SENS button, rotate the
command dial in either direction to alter
the sensitivity.

Sensitivity and film speed
This camera’s shooting sensitivity is equivalent to ISO film speeds of
800 and 1600. Equivalent shutter speed/f-stop combinations can be
calculated based on this ISO rating. For example, to compare
traditional film to digital, at 1/250 second for the same scene
brightness, the E2 might use f/6.7 at ISO 800 which would be
equivalent to f/2.8 at ISO 150 on a regular Nikon SLR.
